Annotation: To determine the effect of a dispersed filler in the form of hydraulic ash removal on the degree of crystallinity of secondary polyethylene terephthalate (PET), a comparative analysis was carried out for PET in its original form (flakes obtained by grinding PET bottles) and after the processes of making samples of polymer composite material (PCM) by thermoforming. The degree of crystallinity of the initial secondary PET was determined from the intensity of the characteristic peaks in the IR spectrogram. For PCM samples, the intensity of the peaks was determined from the data of X-ray phase analysis (XRD). Additionally, to confirm the results obtained by the above methods, the degree of crystallinity was determined by measuring the density of the samples. The results of X-ray phase analysis indicate a significant effect of the filler in the form of hydro-removal ash on the supramolecular structure of secondary PET, in particular, an increase in the degree of crystallinity when PET is filled with modified hydro-removal ash by 24,39 % in comparison with the unfilled polymer.
Keywords: polymer composite material, recycled polyethylene terephthalate, ash from thermal power plants, degree of crystallinity.
